Overview
Description
The SLG47004 is an AnalogPAK™ programmable mixed-signal IC with operational amplifiers, digital rheostats, EEPROM, and a wide set of analog and digital macrocells.
SLG47004 builds upon the flexibility of the GreenPAK’s traditional mixed-signal solution by integrating a mix of advanced analog features, including op amps with programmable bandwidth, 10-bit digital rheostats, analog switches, and a chopper analog comparator. The unique Auto-Trim feature highlights the ability of this GreenPAK device to periodically tune its rheostat value to either compensate for system error sources or reconfigure circuit parameters. The SLG47004 provides dynamic Power Down control for all analog and digital blocks to optimize power consumption performance. Common applications include sensor interfaces, ADC analog front-ends, configurable amplifiers, tunable filters, and a variety of other analog circuits. This multi-time programmable solution is built into a tiny 3mm x 3mm package.

Learn how to Implement Simple Tracking ADC based on the Unique Analog Blocks within the SLG47004
Check out a new app note below that describes the implementation of a simple tracking ADC based on digital rheostats of the SLG47004. No external components and no special tuning procedure are required for the proposed ADC structure. Also, the circuit has much better PSRR and temperature drift than a ...

SLG47004 Op Amp Buffer
GreenPAK Designer v.6.25 SLG47004 I am using OPAMP0 as a non-inverting buffer for an analogue input. It appears that if I allow the input to drop to 0V then the OPAMP output seems to turn off and does not turn on again until 5 or 6mS after ...

SLG47004 Demo Project - GreenPAK
GreenPAK dosen't work when I open Analog Front-End for Electrocardiogram Monitor AN-CM-326 project. I think OpAMP causes that. Because same thing happened before. Also I'm a Linux user. Might Ubuntu 22.04 cause for working problem of designer? Any advice?
